- Rewrite pending SRB handling and change some behavior of the IRP queue
- The caller is no longer responsible for checking whether it can call USBSTOR_QueueNextRequest; frozen IRP queue and pending SRB are both handled for them
- It's no longer required for the caller of USBSTOR_QueueTerminateRequest to know whether the SRB was active (which was impossible before when handling a cancellation)
- Many potential race issues with IRP cancellation are eliminated
- Debugging hung SRBs is much easier now that pointer to the active one is stored in the FDO
